forgot to mention
As Knight is chr reliant and gets d12 a fine combo is knight/'divine crusader' (complete divine). Nothing quite like moving into 9the level big boy spell casting along with the so called 'casters' after a happy, safe, robust first 7 levels as a knight with no 'i'm dying','i need help' cry babying.
Strength is a fine domain. Dream Dwarf/Knight/Divine Crusader 10/Dwarven Defender 2/Deepwarden (Races of Stone) is a fine, fine build!! Defense/Offence (range and close), specialisation, immunities, robust etc..
